nope all you have to do is move the batt. back, and kinda compress the tube at the flex part. works great

Let me know if you want that Saab intake. I'm on my second order. I'm just not selling them on your Saab forum.

You won't find a nicer one.
-------sorry if this is not in the right thread----------
i dont know if you guys that have problem with hesitation with cold air intake on protege 1.6l ??: i had this problem too since i installed it, here is the solution :
the MAF is mostly the cause, but hes doin his job ok. it calculate the air flow that passes in the pipe and tells the ecu how much fuel to pump in engine,
since the stock intake pipe ( rubber one) is smaller (diameter), when the engine suck its 1.6l from the tube, the air travel much faster in the stock intake,
most cold air uses metal piping witch have an inside diameter a little bigger than factory so the same amount of air (1.6liter) travel much slower when passing thru MAF. ( try blowing in straw vs blowing in a scott towel pipe, the air goes faster in the straw)
so here is what i did to overcome the MAF from sending that there is low airflow when the engine actually gets the same amount of air (or more) into the engine :
in the piping where the MAF is located, i inserted a 2" rubber pipe for plumbing, used for coupling 2 pipes together that i bought in home depot (7$)
the fit was really tight... where the MAF hole is, i cut a new hole in the rubber tube to inserted back in place the MAF,
result : at the MAF location in the intake tube the diameter is slightly smaller so at that place the airflow is augmented, thus the MAF read correct airflow, sending correct data to ecu witch shoot right amount of fuel.
no hesitation when at partial throttle, or cruising highway. the power curve is more steady too. not like before : "underpowered then bam!, OH there is my 105 HP!"
if you need more explanation just ask.
Thanks

i just recently fixed mines too. i made an inner tube patch gasket on the MAF mounting surface. probly works good as urs if not better. wanna race? :-D

u shud of done that w/o considering
Crap...
at low thottle/gas its fine, but now my idle stumbles...
by the way, when they say "leak in the MAF region" does it need to be a big leak? because i notice that my maf gasket is a little damaged... that can't be good right? anyway i'm thinking goin to a scrap yard to get factory airbox back and do the same setup as redpro99..

Have any pics of this fix? So you basically bought a 2" coupler, slid that over the opening where the MAF sensor goes and then cut out the hole to put the MAF back in place again, right?

9 hp from an intake on a 1.6L...you got a dyno to back that up?
If not, how did you determine this, please explain.

i have the weapon-r short ram also. did u put urs right on? i had to use the inner tube MAf gasket trick. i tried adding an elbow to it, and it worked fine at first, but now the idle went bad, and the accelaration was bouncy. i had to go back to stock. im gonna try just the regular piping again. i only did the elbow cause they locate the filter right infront of the radiator.
